Bộ chuyển đổi khí ZDL03 NO2/ NO gas converter trong phân tích khí Fuji

 

• Catalyst  : Carbon, replacement required every 8 months (when N0₂ concentration is 10 ppm or lower)
• Gas flow rate : About 0.5L/min.
• Set temperature : 220±10°C
• Thermocouple    : K
• Power supply :100V AC, 50/60Hz
• Power consumption : About 85VA
• Material of parts fhat contact gas : Ceramic, Viton, Glass wool, SUS316
• Gas inlet/outlet connection method : Insert Teflon tube ⱷ6 mm/ⱷ4 mm into Viton connection port of inner diameter ⱷ5.5 mm. (Withstand pressure: l0 kPa)

This gas converter is composed of the converter block and the temperature regulator block.
3.  Installation, Piping, Wiring
(1)       The main frame should be installed vertically to the ground. Avoid installing it obliquely or laying it on its side. Be careful not to apply load to the joints at the top and the bottom.
(2)       Pipes should be connected so that the bottom port of converter block becomes an inlet and the top port becomes an outlet. (Refer to “3. Outline Drawing.”)
(3)       Connect power supply to the terminals indicated in the wiring diagram. (Use type D for grounding.)
(4)       Install fuse or power switch separately.
(5)       Confirm the piping and wiring before turning ON the converter.
(6)       Be careful of the high temperature after turning the power on. The temperature regulator ([*]) is set at 220°C. Since temperature has been factory-set, the temperature regulator need not be operated.
(b)     Under SV (Set Value) display, set 220°C by pressing the [A] or 0 key and determine it by the
I ENT | key. (200°C need be set for NO/CO analyzer.)
(c)      Run automatic tuning when temperature is unstable.
(d)     The temperature controller controls converter temperature through the SSR relay.
4.  How to Replace Catalyst


During catalyst replacement, carefully protect your body from a burn because the converter block is hot.
Catalyst and filter should be replaced with new ones once
every eight months, (when flow rate is 0.5L/min or lower
and NO2 concentration is 10 ppm or lower)
(1)      Turn off the main power supply for converter.
(2)      When it has cooled down, remove One touch band from the upper joint (1) shown in Fig. 2 with a pair of pliers or other apparatus. The lower joint (1) can be easily removed by shifting it gradually with a blade-edge screwdriver. Attention should be paid not to damage the ceramic heater.
(3)      Pull out the metal fitting plates (2).
[CAUTION] Place a catch pan or sort to receive the falling catalyst (3) and glass wools (4).
(4)      Place (4) at the end of metal fitting plate (long) (2), insert it from the lower side of the ceramic heater, then inject the new (3) from the top, using a funnel or alike.
(5)      Attach new joints (1) and (5) to the heater and reconnect it to piping, then fasten all the straps of the bands. Turn ON the power supply.
